APPLICATION INFORMATIONS
A 4.7 F (or greater) capacitor is required between
the AIC1740 output and ground for stability.
Without this capacitor the part will oscillate. Even
though most types of capacitor may work, the
equivalent series resistance (ESR) should be held
to 5
Many Aluminum electrolytics have electrolytes that
freeze at about -30 C, so solid tantalums are

recommended for operation below -25 C. The
value of this capacitor may be increased without
limit.
A 0.1 F capacitor (or greater) should be placed
from the AIC1740 input to ground if the lead
inductance between the input and power source
exceeds 500nH (approximately 10 inches of trace).
